See changes to test.capnp for example.

Currently only supported through generated code, not in the dynamic API. Not exactly sure how to expose this in the dynamic API...

Note that embedded schema structures in generated code are still incorrect.

More refactoring is needed, but this at least makes "using" aliases work correctly with generics.

Actually, let's use single digits for these otherwise they'll actually be printed in scientific notation with a '.', defeating the purpose of the test.

Appending 'f' to an integer literal doesn't make it a float. We have to add '.0' first.

Fixes #119.

Fix obscure bug where the last outgoing message (and any capabilities therein) would not get released (until a new message was sent, replacing it as the last).

This took hours to track down, because it initially looked like "Release" messages weren't being honored in some cases (when they happened to be releasing a capability from the last message, and no subsequent messages were sent). Initial attempts to capture this in a unit test failed because the test of course used a subsequent call to detect if the capability had been released, which succeeded.

The license change is practically meaningless, as MIT and BSD 2-clause are legally equivalent. However, the BSD 2-clause license is sometimes confused for its ugly siblings, BSD 3-clause and BSD 4-clause. The MIT license is more immediately recognizeable for what it is.

Rémy Blank and Jason Choy (the two non-trivial contributors) are on record as approving this change:

Implement opt-in cancellation for local calls.  (Previously, cancellation would happen whether or not the callee had opted in.)

Tail calls half-implemented, but I think it's time to delete all the cancellation code before continuing because it will simplify things.

In RPC protocol, rename request -> params, answer -> results.  Also fix up Join stuff in rpc-twoparty.capnp, because it was sort of wrong.

Remove 'has' for primitive fields.  Dynamic version always returns true.  This also means that primitives are always included in text format, even if they are default-valued.

Implement two-party network.  The first RPC call over a socket took place at 2013-11-08 14:46:43 -0800 and completed successfully.

Interface code generation.  Also update method grammar to allow multiple returns, and allow specifying request/response structs instead of parameter lists.

Extend interface grammar to support inheritance, and update compiler to properly compile interfaces.

Actually fix the bug, which was a doozy:  OrphanBuilder::tag was sometimes initialized using WirePointer::setKindAndTarget(), but since the tag didn't live inside the target segment, this used illegal pointer arithmetic.  The target is never read from an orphan tag anyway, so I thought it would be no big deal.  But it turns out Clang actually optimizes under the assumption that pointer arithmetic returns a whole value.  As a result, on 32-bit system where 64-bit values are only 32-bit aligned, the tag and target might not have been a whole number of words apart, and the extra bit actually found its way into the 'kind' bits, causing e.g. a struct pointer to become an invalid far pointer.  Crash.  The fix required refactoring to ensure that setKindAndOffset() is never used for orphan tags.

Require a colon before 'group' or 'union' except for unnamed unions as well as the legacy case of a named union with an ordinal (where the colon is optional).

Generate usable code for groups, although making schemas work is still an open problem.  I think I'm going to do the schema rewrite now.
